This paper describes a machinability testing method developed during a co-operative research program at Battelle Memorial Institute sponsored by The Carnegie-Illinois Steel Corporation. The test evaluates materials on the basis of the feed resulting from a fixed horizontal tool pressure. Its advantage is that it requires only a short testing time. A description of the lathe and auxiliary equipment is given, and typical testing results are presented. The data indicate that the method has a high order of sensitivity and adequate reproducibility of test ratings. Constant-tool-pressure machinability-test ratings were in close agreement with tool-life test values when the evidence indicated reliable sampling, and in adequate agreement with large-scale commercial machining operations. The test seems to offer a means of rating the cutting quality of free-cutting steels rapidly and reliably with the use of small samples. |
